Popover: Scoped stylings via [dt] don't get applied

[gregorwinkler]

Describe the bug

I'm trying to add a custom styling for a p-popover in one view, thus I wanted to use the [dt]-property to have a scoped styling.

But it doesn't seem to be applied, at least all the tokens are ignored, see the Stackblitz examples for details.
